Abstract:

With the rapid evolution of generative artificial intelligence technology, data quality has become the core bottleneck restricting the performance of industry-scale large language models. Telecom operators possess ZB-scale cross-domain data, providing inherent resource advantages for training vertical large language models. However, raw communications data generally faces issues such as multi-source heterogeneity, high redundancy, and scarcity of long-tail samples, which limits its effectiveness when directly applied to model training. To address this, the system proposes a high-quality dataset construction method encompassing “collection—governance-annotation-evaluation,” featuring key technologies such as deep semantic compression, long-tail data synthesis based on Wasserstein Generative Adversarial Network (WGAN) and Long Short-Term Memory (LSTM) network, domain ontology construction, and human-machine collaborative annotation. Meanwhile, a general and specialized knowledge data coordination mechanism is designed to effectively mitigate catastrophic forgetting during industry fine-tuning. Practice has proved that this method is effective and can provide reference for the construction of high-quality datasets in the telecommunications industry.
